MAX6369KA+T

MAX6369KA+T is the lead-free tape-and-reel ordering code for the Analog Devices MAX6369 pin-selectable watchdog timer, defined in the ordering information of the maker’s MAX6369–MAX6374 datasheet itself: the table lists the base code for the 8-pin SOT-23 (top mark AADC, -40 °C to +125 °C) and states in the same table that the lead-free form is ordered by replacing the -T suffix with +T, which is exactly the code listed here. It runs from 2.5 V to 5.5 V on a supply current of 8 µA typical and 20 µA maximum, offers pin-selectable watchdog timeout and startup delay periods from 1 ms to 60 s (minimum) with the startup delay equal to the timeout period, and drives its watchdog output as an open-drain pulse of 100 ms. The selection point is supervision with no firmware and no external timing parts: three pins strap the timeout, so the same code covers everything from fast-start controllers to slow-boot processors across a product line. Selection advice: the timeout is set by pin strapping, not by a suffix - confirm the strap table of the datasheet against your boot time, because a watchdog that fires during a legitimate slow startup is a board-level fault, not a component fault. Parameters verified against the Analog Devices MAX6369–MAX6374 datasheet (ordering information and electrical characteristics).
